    Hi guys,

    I have a question regarding the dynamic voltage offset setting of 4810mq in xtu. When I first got my laptop I noticed that my 4810mq would not run at 3.6ghz at full load. After researching over the web, I learned the fact that hasswell CPUs have default voltage way higher than needed. So I tried to tweak the voltage and other parameters in xtu. My question is that, how do I determine the optimal voltage for my chip(since a wide range of voltage offset values can give me stable performance ).

    Thank you all in advance.

    The lowest possible value where it is stable (plus a step or two for safety).

    Thanks. Is there any reference for this kind rules? For example, if I run it at -75mv or -50mv ( both stable) long term, would there be permanent damage to the CPU ?

    Lowering voltage extends life span, raising it decreases it.
